Renal Cell Carcinoma (RCC) is the most common type of kidney cancer, accounts for about 85% of all kidney cancers and is commonly diagnosed in adults.
Risk Factors:
- Smoking: Significantly increases the risk of RCC.
- Obesity: Linked to higher RCC risk due to changes in hormone levels.
- Hypertension: High blood pressure is associated with an increased risk of kidney cancer.
Common Signs and Symptoms of Kidney Cancer
- Blood in the urine (hematuria): One of the most common symptoms.
- Back or side pain: Pain in the side or lower back that doesn't go away.
- Lump or mass: A palpable lump or mass in the side or abdomen may be present.
- Unintentional weight loss: Significant and unexplained weight loss can be a symptom.
- Fatigue: Feeling tired or lethargic without an obvious cause.
It’s not necessary of the above symptoms will be cancer but it's crucial to consult with a healthcare professional if any one finds such symptoms.
Diagnosis of Renal Cell Carcinoma (RCC) often involves imaging studies such as CT scans, MRIs, or ultrasounds, as well as a biopsy to determine whether the tumor is cancerous. Treatment options for kidney tumors depend on factors such as the type of tumor, its size, and whether it has spread to other organs. Treatment may include surgery, radiation therapy, chemotherapy, immunotherapy, or Microwave ablation (which is the latest and is minimally invasive means without big cut or scar on our skin).
Treatment Options:
Surgery: The primary treatment for localized RCC.
- Partial Nephrectomy: Removal of the tumor with a margin of healthy tissue, sparing the rest of the kidney.
- Radical Nephrectomy: Complete removal of the affected kidney, sometimes including the adrenal gland and surrounding tissue.
Ablation Therapies:
- Microwave Ablation (MWA): Microwaves energy is used to heat and destroy the tumor. It’s faster Minimally invasive, short recovery time without cut or big scar on body. Normally patient is discharged within 24
When and why to choose Microwave ablation for Renal Cell Carcinoma.
Microwave ablation is a minimally invasive technique used in the treatment of kidney tumors. The goal of microwave ablation is to destroy cancerous or abnormal cells in the kidney using high-frequency of microwave energy.
Advantages of Microwave over surgeries
Minimally Invasive Procedure
A thin needle is inserted into the tumor through the skin, guided by imaging techniques such as ultrasound or CT scans. This approach significantly reduces the need for major surgery, leading to less trauma for the patient.
Reduced Recovery Time
Patients undergoing microwave ablation typically experience a quicker recovery compared to those who have surgical resection. Many can return to their normal activities within 24 to 48 hours post-procedure.
Lower Risk of Complications
MWA is associated with fewer complications than surgical options. The risks of significant bleeding, infection, and damage to surrounding organs are considerably lower. For instance, the risk of complications during MWA is less than 1%, making it a safer option for many patients, especially those with comorbidities or those who are elderly.
Effective for Small Tumors
Research indicates that MWA is particularly effective for small renal tumors. The cure rates for these tumors are comparable to those achieved through surgical methods, with high technical success and efficacy rates reported in clinical studies.
Repeatability
MWA can be performed multiple times if necessary, making it suitable for patients with recurrent tumors.
Preservation of Renal Function
Unlike surgical resection, which may involve the removal of a portion of the kidney, MWA primarily targets the tumor while preserving surrounding healthy kidney tissue. This is particularly beneficial for patients with compromised kidney function or those who wish to maintain as much renal tissue as possible.
